Be it known that I, COLIN MAORAE- INGER` SOLL, a. citien of theUnitedStates, residing at New York city. York and State of New York,have invented certain new and useful Improvements in Machines forSurfacing Roads, Pavements, &c., of which the following is aspecification, refereiice being had therein to the accompanyingdrawings. i p l This invention relates ltova machine for applying aliquid bonding and. surfacingniaterial to macadam or other beds ofroads, pavements vand the like, whereby the ingredients of the upperstratum or` strataof the beds are bonded together and given a finishingsurface through which dirt and waterdo not work.- Thev material used ispreferably coal-tar or a tarry composition. Road and pavement beds lthus vtreated dry quickly after ra-infalls, and are readily cleaned andrepaired. y i

Among the objects ofthe present inven-l tionV are: the provision of asurfacing'machine that is economical to construct, opera-te andmaintain, and that is adapted to heat and apply hot., tarry-like bondingand surfacing material, under pressure, so that it penetrates downwardlybetween the macadam or other roadbed constituents, 'and thoroughly bondsand covers them; and also to make the machine in such wise that it isnot dependent'on local .watersupplies for maintenance rof its principaloperations dui'- ing its tours of use. i j l.

M vnew machine comprises thefollowing principal factors, which are herestated for better understandjii'gof the .followingdescription:-a wheeledvehicle; a* driving mechanismM therefor; an internal combustion engine;`an air compressor; a reservoir Ito holdtlie bonding and surfacingmaterial; a` discharging device for such material; a

road-cleaning brush in advance ofthe `discharging device ;l anddrag-brushes rearward of the discharging device; th eXh ustA gases ofthe engine being usedzat w ll to ieat the contents of the reservoir; thea'ir conipressor being used, at will, notuonly to supply compressed airabove thecoiitey's of the reservoir and thus secure the uni ,'orin4dis`` charge of the material undef; pressure, but also, when desired,to charge the reservoir automatically. VSuitable clutches or the likeare provided toconnect and diyomect the air compressor, engine anddriving-gear, so .i bustion engine mounted on the frame; I)y

in thecounty of Newv the reservoir,

lthe discharging heads ofthe reservoir.

Ar compressed air tank isv also preferably provided, between the aircompressor land to supply compressed air to the upper part of thereservoir, above its contents, when the compressor is not in operation.i i

` In the accompanying drawings, illustrating the Vrinciple of theinvention and the best m0 e now know'nito meof applying that the samemay bev run either simultan u ously or independently as may berequired.v

that principle, Figure 1 is, an elevation of the' machine, .partly inside view and partly in vertical section, at aline corresponding to line1 1 ofFig. 3. This view also shows a container of the road bondingandsurfacing materiah exterior to the machine, and

`from which the material may be automat-- ically conveyed totheireservoir to charge-it.

Fig. 2 is an enlarged View, partly in side elevation and partly invertical section, at

Fig. 11 is an enlarged View moreclearly showing the connections of theengine with the .road-cleaningbrush and with the air compressor, and, on the lengine shaft, theactuating gear of the ve- -hicle driving mechanism. Fig. 12 is a vcr-Fig. 8 is a vertical, central view lof the air compressor, showing itsinlet and the rear axle of the machine, the rear wheels of which aredriven from the engine; F an air compressor; R the reservoir which convta'ins the bonding and surfacing material; l andfC a compressed an'tank whlch 1s 1n .communication both with the air compressor engagement,bevel-gear 2 rotates with shaft l 1. Collar 4 1s circumt'erentiallygroovedj for reception of a pin (Fig. 2) on lever 6 pivoted at 'i' totheframe Lever 6 is connected to a controlling-rod 8 extending to thedrivers seat, and there attached to a controlling-lever 9 provided witha pawl and v ratchet mechanism 10 for holding it in position to keep thetoothed collars 3 and 4 connected or disconnected.

' The purpose of bevel-gear 2 is to drive the road-cleaning brush 24.Bevel-gear 2 meshes with a bevel-gear 11 en a vertical shaft 12, and itshub 13 rests on the upper side of frame A. l

Shaft 12 passes from A and through a .bearing-plate 14 between the underside of frame A and the upper side of brush-carrier 15, bei-ng provided,on the under side ot' the brush-carrier, withy a fixed collar 1Gwhereby, in connection with hub 13, shaft 12 is kept, from endwisemovement. The lower end of shaft 12 is provided with a bevel-gear 17which meshes with a bevel-gear 18 on the transverse horizontal shaft 19of the brush frame. This shaft is mounted in bearings vin the opposite,downwardly extending endhangers 20, 20 of the brush-carrier.Intermediate bearings 21, 21 tor shaft 19 are preferably provided.Hangers 20 are provided 'each with a hook 21`'c to engage the journals22 of the road-cleaning brush 24 when it is desired to keep `the brushabove the ground.

The journals of the brush are mounted in the vertical slots 25 ofhangers 20, in order to permit the road-cleaning brush to rise in easeit encounters substantial obstacles. One

of the end journals of the brush is provided vwith a sprocket-wheel 26,from which a sprocket chain 2T passes to a sprocket-wheel 2S ona'correspzmding end of shaft 19. Rotation ot' shaft l2 compels the brush24 to rotate and sweep the road-bed.

The roadcleaning brush, when in operation, should stand t'ansversely offrame A, and diagonally in relation to the length thereof, so that thelsw-eepings may be dis-v charged to either side of the road at will.

To lock and brace the brush' supporting frame 15 1n one o r the other ofsuch diagonal passages controlled by said valves.

positions, each side of frame A is provided with a pair of ears 29,against the under surfaces of which the upper surface of the brush framerests and is thereby braced and locked when the brush frame is in adiagonal position and pins are through the coincident holes through theears and brush frame.

rl`he driving mechanism of the machine for connecting the engine withthe driven rear axle l) (Figs. 3 and 4) comprises a short, transverse,horizontal shaft 31 and an auxiliary shaft 31L in alinement with shaft31, mounted in bearings 32 on frame A. The inner end of shaft 31 isprovided with a fixed bevel-gear 33 which meshes with a bevel-gear 34fast on engine shaft 1. The outer end of shaft 31a is provided with alixed sprocket wheel 35, from which a sprocket-chain 3G passes to asprocket-wheel 37 on axle l). Shafts 31 and 31 are coupled together forpropulsion of the im chine, shaft 31a being provided with Pa lixedcoupling member 3S and shaft 31 being provided with a .slidable couplingmember Si) 'cireumferentially grooved for the reception of an end 40 ofbell-crank lever 41 pivoted at 42 to frame A controlling-rod til extendsfroin the bell-crank lever t'orwardly to the drivers seat, where it isprovided with a controlling-lever 44 and a suitable pawl and ratchetmechanism. By this construction the driving gear may be disconnectedtrom the engine whenever desired, so that the machine as a whole mayremain stationary, the. engine shaft then being t'ree to rotate, whendesired, without propelling the machine, in order to operate aircompressor l" while the vehicle is stationary.

Shaft 45 .of the air compressor (Fig. .11) is extended on one side inalinement with engine shaft, 1, and provided with a slidable clutchcollar 4U. which is compelled to rotate with shaft 45 by a spline 46"'and which is adapted to engage with the supplementary clutch member 4i'fast on shaft 1, whereby the engine shaft and air con'ipressor .shaftare coupled together. Clutch collar `ttl has a` circumferential groovetor reception ot pins 4S in yoke lever 49 pivoted to frame A at 50.Clutch collar 46 may thus be disconnected from clutch member 47 when itis not desired to operate the air compressor.

The. cylinder of the air compressor (Fig. S) is provided with a head 51.in which an outwardly opening valve 52 and an inwardly opening valve 53are mounted in a well known manner, head 51 being formed with Fromchamber 54 of this cylinder. (Fig. 1), a pipe 55 leads to the compressedair tank C, being provided, between' the '('f'in'upressor and air tank,with a shut-olf valve 50.

53 controls a pipe 5T that is open v'to the air and provided with a.shutoil' valve 58. When valves 56 and 5S are open andl the The valve'piston 59 of the compressor is given a downstroke, the air in chamber 5lis rarefied, and atmospherlc pressure through pipe funseats valve 525.permitting inow of outside l l i i l air into said chamber. Onthe-up-strokef of piston :39, valve 53 is seated a-nd valve. 5:2unseated, and air is pushedthrough pipe into the compressed Vairchamber, which is f provided with a suitable pressure-indicator (it) (lthe details of which are not illust ated, it not being' deemed necessaryto show the construction, as the same `will be readily understood by allskilled in the art) toshow 'the pressure inthe airtank.

ln the operation ot the air compressor,

heat willhe generated, and thecylix'ider and piston consequently heated.I therefore prefer to provide the air compressorwith some simple forniof evaporatrng device whereby the cylinderniayV be cooled ;'but,`forthereai son that machines containing my invention maybe frequently'operated at considerable distances from adequate Water supplies, (whichwould be requisite for a steam-operated machine.) l do not. wish towater-jacket ration of cloth n2. As theair compressor isl only inoccasional operation, this simple evaporating device servestosuticientlycool the cylinder. Trough (l'catches any drippings there may be, and byholding the drip water in contact with the cylinderfacilitates thecooling thereof. Any other evaporating or coolingv devicerinay he usedif rand When any cooling` of the air compressor is neeessary.

Compressed air tank C preferably surrounds reservoir R. in order toreduce the radiation of heat therefrom, 'and is connected by a pipe 66with the upper part of the resmwiir. The pipe is provided with ashut-ott cock GT; While compressed air tank (j forms. in etl'ec-t, apart of the conduit connection between air compressor F and reservoir t.vet the air tank isv'desirably interpo ed.heeause but little pressure ofeompressed air in the upper part ofA reservoir It, above its contents,is requisite to secure av uniform discharge Yofwthe contents underpressure; and also-because the air pressure would not beso uniform ifthe air compressor were run continuously and piped directly to thereservir.-A Therefore. when compressed air tank C is charged, valve 5Gmay be closed and valve 67 opened. and 'the pressure of the compressedair in tank Cloe 0n any suitable support, a i

the material is not sufficiently forcible, valve may be opened and@ theair compressor operated. 68 is the flywheel of the coinpressor, and 69the ity-Wheel of the engine.

lReservoir R- is provided, at its upper portion, with a .short pipe 70,which provided with a sh ut-otf cock T1; The purpose of this pipe 70 istwo-fold. It'lfl allows gasesand' fumes generated in the reservoir toescape and he observed, and it is als'oused as the feed-intake of thereservoir when the latter is charged. 4When the reservoir has beenproperlycharged,that is, to a line soulewhat below its upper euch-andthe material is heated. gases and fumes which can be-observed willes'eapethrough pipe 70, valve 711,.-

being lthenopen. The appearance of v,gases end of pipe 70 shows whenlthe saine 'is sutficiently hot for mostI eti'fec'ztlve application,

and then valve Tl isclosed and yvalve GT opened to 'let in compressedair, whereby the, Vheated contents of the reservoir are forciblyexpelled. through the downwardly extending discharge exit 77, at therear end of the machine and rearwardof the/road-cleaning brush. Thelower endaportion'of exit 7 7 is provided with a shut-0H 'valvev 8,which .is actuated by a controlling-rod 79;-tliat passes forwardly to apoint near thedrivers seat and vis there connected with a lhand lever 80whereby valve 78, is conveniently opened or closed. f y

To heat. the contents of the reservoir, the escape gas-exhaust 8l of theengine is provided` with a two-way dischargepipe or inuliler), onebranch SQofWhieh discharges into the open air adjacentto the engine andis provided with a shut-off' valve. 83. The other branch 84e passesrearwardly into heats ing proximity or relation to theA reservoir, sothat when valve`83 is shut, the exhaust. gases of the engine are availedof for heating the contents of the-reservoir. Branch 84 is pro-`videdavith a shut-,off valve 85, so that. when it is desired toturn ottheat from the reservoir the exhaust `gases may be discharged throughbranch 82, the valve 83 being open. Preferably, branch 84 is passedthrough the bot-tom of reservoir R and extended into a ehamberedcontainer 86. T his container is Within the bottom portion ofthe supplyvreservoir. A series of pipes 87 `pass from the container upwardlythrough the reservoir and discharge into the open air... above the topthereof. Y The cross-sectional areas of branches 82. 84, the, capacityof the exhaust- `as arrester Sound the cross-sectional areas yof pipes87 should be snflieient to allow the exhaust gases from the engine toescape Without back pressure on the engine. rl`he arrester is ofconsiderable dimensions, so as communicated to theupper surface ofthe topresent a .Qood amount of heated surface contents of the reservoir Rduring` the fall l to Vthe contents of the, reservoir. It is ohtnereof1n the reservolr. If the outlow of i. vious that such use of thehotgases 1n this i and fumes of coal-tar or the like at the open 'i Itached, by preference, a plurality of distributer-heads 89, in line onewith another and of identical'.construction. Practically threedistrihuter-heads are suiiicient, -and of course gone continuous'distributer-head might be used. 'In thatcase, however, the machinewould frequently discharge su eriiuous material; for example, where on ya narrow strip of the road-bed needed to be `treated This considerationapplies more largely to repairing operations than it does to the initialsurfacing of the road.

Flach head is preferably hinged at 90 (F1gs. ,1; y12"and 13) to thedistributingpipe 88, the tubular neck 91 of the head havingatransversetubular portion 92 which is rockably mounted in a section 93 of pipe 88,this section 93 being a transverse tubular head on the lower end ofdischarge 77 and inclosing the part 92, which has an opening 94C forflow of material from discharge 77 into part 92 with which the tubularneck 91 f communicates. Screw collars 95 couple sections of pipe 88 withthe interposed transverse tubular head 93, which is circumferentiallyslotted at 96 to allow neck 91 to swing up and down in relation todistributing-pipe 88. Thus the distributer-heads will be lifted if theyencounter an undue obstacle; or if it is desired to have them in raisedposition for any reason. A chain attachment 97 on frame A suflices tokeep a head lifted (see Fig. 1). Each head is preferably provided with abracket 98, against which the head abuts when in its lower ordischarging position. A spring 99 attached to the bracket and to thehead serves to hold the head in its proper discharging position againstbracket 98. Each head is provided, in its tubular neck, with a shut-offvalve 100. The distributer-heads are each preferably provided withdownwardly and inwardly slanting side-walls 101, and are open on theirunder sides throughout their length for reception ofan internalroof-shaped bottom 102, the bottom being secured to the end walls of thehead, and the ,long sides of the bottom being removed from the opposededges of the side-walls 101 so as to form two continuous parallel exits103 along the under side of the distributer-head. The inclination ofeach side-wall of the roof-shaped bottom to a downwardly and inwardlyslanting wall 101 forms, along each side of the ldistributer-head, atrough through which the surfacing material is directed to the extendingslot 104, between its ends, these slots each forming a guide-way for aslideplate 105 which projects from a slot to, into or across an exit foreither opening or partially closing the same. The outer surface --ofeach wall 101 is provided with a vertical slot 106, through which a stud107 extends from a slide-plate. An adjusting-screw 108 is connected tothe outer endot each stud and passed through an internally threaded ear109 projecting from the head. By turning the screw, the slide-plateconnected therewith may be moved into any desired position to close oropen an exit. hese discharge-heads may be made of any desired length,and, as above noted, one of them may be used in lieu of a plurality ofthem. When a plurality of heads are used, it is desirable that theopposite end portions of the exits 103 have endwise openings 103* (seeFig. 7), in order that the opposed end discharges of adjacent heads mayintermingle, and so surface the road-bed along spaces corresponding tothe distances between opposed ends of the distributer-heads. Ifprovision of this sort were not made, then there would be danger, aswill be apparent from Fig. 3, of the road-bed not being surfaced alongsuch spaces.

The hot tarry or other surfacing material having been forciblydischarged on the roadbed, it remains to brush in this material; and forthis purpose, rearwardly of the discharging-heads, two series ofbrushing-in brushes 110 are used. The members of each series of brushesare in line one with another, but at intervals apart; each member oftherearmost series being mounted opposite the 1nterval Abetween two membersof the first series, so that a uniform brushing-in of the surfacingmaterial from side to side thereof is secured. Thesebrushes are eachpreferably hinged at 111, at its front edge, t0 a drag-rod 112 fast atits upper end on a transverse rocker-bar 113 mounted in side brackets114 at the rear of frame A. Brushes 110 should be fairly heavy, and maybe weighted whenever desired. Their purpose is to 'compress, brush-inand finish the surface of the hot or warm surfacing material.

The road-cleaning brush and the brushingin brushes are in contact withthe road surface, but use of the road-cleaning brush is not alwaysrequired. To accommodate the machine to various positions when not inuse for surfacing, and also to permit the brushing-in brushes to rise incase they hit a substantial obstacle, and to hold the drag-rods lay andinconvenience of heat-ing tar beforel tion of the exhaust 465 forapplying dissimilarcompositions.

and brushing-inv brushes in an elevated posis tion, a cross-bar 115 isattached to-the brackets k114 and hooks 116 mounted therein forreception of the dra ply reservoir isordinarily lto be charged will varyin consistency according to their4 ingredientsand under varyingtem-peramentalv conditions. Generally, however, the tar or tari-ycompositions willbe more or less thick and sticky; It would ofcourse bepossible to heatV the 'tar or tarry compositions, and thus render themfluid enoughV to 'be readily pumped into the-supply reservoir. In thepractical 'operation of myfmachine I propose,l

however, in ordertoobviatc the expense, de-

introducingit into the reservoir, to put it up in practicallyair-tightcontainers'which are to be distributed along theside ofl theroad Vto Abe treated,"at convenient intervals, whence it will beautomatically'conveyed to the reservoir asfrequired.' Y In order toaccomplish the economical and convenient charging of the reservoir underthese conditions, I provide the container 200` (see Fig. l) with twobung-holes in Van upper side, and through one of them insert the nozzle201 of a detachable pipe 202, the nozzle reaching to near the bottom ofthe container.` The other end of the pipe is attached to the tube of thereservolr, and valve 7l opened. Into the other bung-hole of thecontainer I insert a short nozzle 203 of a detachable pipe 204, andattach the otherend of this'pi'pe to a compressed air-outlet 205 fromthe compressed Aair tank, this outlet being provided with a shut-oli'valve 206 which is opened when the charging is to .take place.V Valve,67 being closed and valves 206 and 7l opened, compressed air will flowthrough pipe 204 against the upper portion of the contents oi container'200, whereby the contents are forced through pipe 202 and pipe 7 0 intothe reservoir lt to charge it, the inan-hole cover being open to let'air out of the reservoir. The principle here involved of charging thereservoir may obviously be carried out in steamoperated road-surfacingmachines; for steam from a steam generator passing through pipe 204.would push the contents of the container into the reservoir, j ust asthecompressed air does. Therefore Idesi-re to claim this feature of myinvention broadly, whetherl the expansiveluid generated and availed ofis compressed air or steam, or any'other eX- pansive fluid under head orpressure.

I make no claim herein for the combinay gas escape of an internalcombustion engine.
